Not allow companies to make their employees that endure labor intense work, to work on sundays. (welders,mechanics, ect)

labor intensive job's take a toll on the body, As there is a labor law for children under the age of 18, there should be a general law for these labor intensive job just as welding, laborers, construction, plumbing, HVAC, mechanic, ect. for a maximum amount of hours worked in so many day's.
